Description
Technical field
The utility model relates to a kind of oilfield pumping well collision pump that is used for the oil-field oil pumper technical field.
Background technology
Bumping pump is to recover the oil to patrol the important process of well normal management on work day, have at oil well under the situation of producing fluid level, because of valve and valve seat are stained with sand, wax, asphalitine, solid or colloid materials such as greasy filth piece, the capital makes the leakage of oil well pump valve, reduce the pump efficiency of oil well pump, bumping pump is the effective ways of removing valve and this class dirt of valve seat, it is present that to bump pumping method labour intensity big, dangerous big, safety factor is little, publication number 1355373, application number 00133614.2, open day 2002.06.26, disclose a kind of oil production machine and bumped pump, the control method of dead space, safe and reliable, crash pump and dead space of programmable controller can carry out accurate Calculation and measurement, realized automatic control, but involve great expense, it is unrealistic that every mouthful of well is joined a cover, publication number 2475849, application number 012203823, an open day 2002.02.06 discloses the automatic collision pump of a kind of downhole pump, automatically bump pump when having realized the oil pumper operation, but be installed in the bottom of oil well pump, maintenance is complicated, bump pump for a long time and easily make pumping rod disengaging, limited penetration and promotion, publication number 2628722, application number 03263963.5, an open day 2004.07.28 discloses a kind of adjustable anti-impact stroke type polished rod touching pump device, realized bumping people of pump operation, but leading screw rotational structure entire length is excessive, can causes bar phenomenon backlight after making it be installed on the polished rod eye, leading screw bears very big load, use afterburning thick stick personnel selection also to be difficult to rotary screw rod polished rod jack-up, the length of afterburning thick stick is subjected to easy to use, the principle restriction, polished rod jack-up is wasted time and energy, bearing is easily damaged by the impact load of holddown and oily thick formation, maintains time-consuming effort, has limited penetration and promotion.
Summary of the invention
The purpose of this utility model provides a kind of oilfield pumping well collision pump, makes every oil pumper join one, and a people can operate and bump the pump overall process.
For solving above-mentioned task, the technical solution adopted in the utility model is: be connected on (6) stock (3) and quarter butt (5) are sat in the end, polished rod clamp (4) seat is on quarter butt (5), polished rod clamp (4) is fixed on the polished rod (1), and hair plait (2) is fixed on the end seat (6) by hair plait head (7) combination.
The beneficial effects of the utility model are: simple in structure, cheap, need not maintain, and safe and reliable, it is short to bump pump operated time, and it is simple to bump pump operated method, does not damage polished rod when bumping pump.
